Solve the system of linear equations by elimination -x+y=4;x+3y=4
Answers
Answer:
the solution is (-8, 4)
Step-by-step explanation:
Let's use the addition/subtraction method here to eliminate one variable:
-x+y=4
x+3y=4
Combining these two equations results in
4y = 8, so that y = 2. Substituting y = 2 into the second equation, we get:
x + 3(2) = 4, or x = -2.
Then the solution is (-8, 4)

Here is an expression: 2 + 3ⁱ ( Remember what you do when you replace i with a number) Evaluate the expression when i is 1.
Answers
Answer:
The value of the expression when i is 1 is equals to 5.
Step-by-step explanation:
We are given the following expression:
[tex]2 + 3^{i}[/tex]
Evaluate the expression when i is 1.
We replace i by 1. When we elevate a number to the 1, the result is the number we elevate. So
[tex]2 + 3^{i} = 2 + 3^{1} = 2 + 3 = 5[/tex]
The value of the expression when i is 1 is equals to 5.

Which triangle has the largest area?
b)
Work out the area of this triangle.
Give your answer as a decimal.
Answers
Therefore , the solution of the given problem of triangle comes out to be triangle C has the largest area 4.5 square unit.
What precisely is a triangle?Because a triangular has two or more extra parts, it is a polygon. It's shape is a simple rectangular. The only three edges that distinguish a triangle from just a triangle are A, B, and C. A singular area rather than a cube is produced by Euclidean geometry when the edges are not perfectly collinear. A shape is referred to as triangular if it has three sides and three angles. An angle is the point where a quadrilateral's three sides meet. A triangle's sides add up to 180 degrees.
Here,
The largest triangle ,
area wise is:
Triangle C area is:
=> 1/2 * b * h
=> 1/2 * 3*3
=> 9/2
=> 4.5 square unit
which is the largest area as all the other triangles have 4 square unit area.

Answer:
4. 300 5. 7 6. 2
Step-by-step explanation:
In order to solve these problems, we need to plug in x for the missing number. So, we would set it up like this:
[tex]\frac{60 mi}{1 hr} =\frac{x}{5 hr}[/tex]
We would then cross multiply in order to find the value of x. Like this:
60 × 5 = 300
1 × x = 1x
300 = 1x
300 = x
So now we know that x is 300.
We would do the exact same thing for the next question. Plug in x, then solve by cross multiplying:
[tex]\frac{8 hr}{2 days} =\frac{28 hr}{x}[/tex]
8 × x = 8x
2 × 28 = 56
8x = 56
÷8 ÷8
x = 7
We now know that x is 7.
Try the last one on your own. Do the exact same thing I did for the first two. I hope you understand a bit better now. Please let me know if you need any more help. Good luck!

Answer:
[tex]\Huge\boxed{D}[/tex]
Step-by-step explanation:
Hello There!
To find the answer we want to find the trigonometric ratio for each answer choice
important note;
[tex]sin =\frac{opposite}{hypotenuse} \\\\cos=\frac{adjacent}{hypotenuse} \\\\tan=\frac{opposite}{adjacent}[/tex]
for A,
the opposite of angle X is 12 and the adjacent of angle x is 5
so [tex]tanX=\frac{12}{5}[/tex] therefore A is not the answer
for B,
the adjacent of angle x is 5 and the hypotenuse is 13
so [tex]cosX=\frac{5}{13}[/tex] therefore B is not the answer
for C,
the opposite of angle W is 5 and the adjacent of angle W is 12
so [tex]tanW=\frac{5}{12}[/tex] therefore C is not your answer
for D,
the adjacent of angle W is 12 and the hypotenuse is 13
so [tex]cosW=\frac{12}{13}[/tex] therefore D is your answer

a race car is driving under the caution flag at 440 feet per second begins to accelerate at a constant rate after the warning flag. the distance traveled since the warning flag in feet is characterized by 30t^2+440t, where t is the time in seconds after the car starts accelerating again. How long will the car take to travel 150 feet?
Answers
Answer: [tex]\frac{1}{3}\ s[/tex]
Step-by-step explanation:
Given
Distance traveled is [tex]s=30t^2+440t[/tex]
for s=150 ft
[tex]\Rightarrow 30t^2+440t=150[/tex]
[tex]\Rightarrow 30t^2+440t-150=0\\\Rightarrow 3t^2+44t-15=0\\\Rightarrow (3t-1)(t+15)=0\\\Rightarrow t=\dfrac{1}{3}\ s[/tex]

Answers
Answer:
6.9
Step-by-step explanation:
The total payment was 44.35 and Ella bought 6 bags of apples and eggs
eggs cost 2.95 so apples cost 44.35-2.95=41.4
lets call bags "x"
so
6x=41.4 (price)
divide both by 6
x=6.9

The domain of the function is -1 ≤ x ≤ 6 or x ∈ [-1, 6] option (A) -1 ≤ x ≤ 6 is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a given a graph of a function in the picture.
As we can see, the at point x = -1 graph starts, and it has dark dot which means function values exist at x = -1.
Similarly, at x = 6 the function value exist.
The domain of the function:
-1 ≤ x ≤ 6
Thus, the domain of the function is -1 ≤ x ≤ 6 or x ∈ [-1, 6] option (A) -1 ≤ x ≤ 6 is correct.
